HELP! Rhabdophis venoms info needed! (rednecked keelback, etc.)

I am doing a big research paper, and I really need any and all information on the snake genus rhabdophis in the snake family Colubridae. If you aren't familiar with the scientific names, some of the common names are the red-necked keelback and yamakagashi. I really need this info! HELP!
